Definitions

  • the device relates to a method for the continuous crimping of thermoplastic threads, in which the threads are blown in as a bundle of threads by means of a jet of a heated medium by means of a jet nozzle into an elongated curved stuffer box, essentially tangential to the curvature of the stuffer box, at a speed which is greater is the circulation speed of the stuffer box, as well as a device for carrying out the method with a jet nozzle for blowing in a filament bundle by means of a medium jet into an annular, rotatable and drivable stuffer box with a blowing zone for receiving and crimping the filament bundle and a treatment zone for heating or cooling of the filament picked up, and a delivery zone for delivering the crimped Fil noirs to a subsequent conveyor element, for example a cooling drum or stretching roller or conveyor roller.
  • a subsequent conveyor element for example a cooling drum or stretching roller or conveyor roller.
  • thermoplastic filament threads are intensive crimping in the crimping device and durability of the crimp after this process step.
  • This type of crimp is a compression crimping process in which a filament bundle heated by a heated gaseous medium is blown into a compression chamber in order to be brought into a crimp position by means of the delayed conveying speed. In this position, the filament is cooled again below the softening point, so that a permanent crimp remains when the crimped filament bundle is pulled off.
  • Such a method is known, for example, from German publication No. 2110670 known in that a jet nozzle blows the filament substantially tangentially into an elongated, curved, tunnel-like stuffer box, this stuffer box being provided in the circumferential direction of a cooling drum provided with a perforated surface. Cooling air is blown out through this perforated surface, so that the compressed filament, as mentioned above, is cooled in such a way that a permanent crimp is retained therein.
  • German laid-open publication No. 2507752 device shown the task of producing a crimped filament by the heated godets pre-stretched and heated thread is thrown onto a screen wall after leaving a jet nozzle and is pre-crimped in the process.
  • the thread rebounding from the screen wall is then gripped by needles of a circulating belt, so that the pre-crimped thread forms a plug between the needles.
  • the needles then transport the plug into a heating channel which is tapered for the compression of the plug. After the heating channel, the plug is released again by means of a dissolving device.
  • a task of a procedure or One device for the continuous crimping of thermoplastic threads is that the whole process is not only with a perfect technical result, but also as economically as possible, ie with favorable operating conditions and high performance.
  • the operating conditions are improved the less aids such as air have to be used for cooling, or the simpler the device can be built in order to obtain the same technological result with high performance.
  • the technological result shows the crimp density and the resistance of the crimp in the filament bundle in the later process steps.
  • the invention solves this problem by procedurally designing the stuffer box in such a way that the medium required for crimping can emerge on all sides from the bundle of threads located in the stuffer box and device-wise in that the stuffer box has two air-permeable, annular, spaced apart from one another Wheel arranged walls, between which the jet nozzle opens tangentially to the circumferential surface of the wheel forming the bottom of the stuffer box, but at a distance therefrom such that the filament bundle between the both walls is held so that it is neither on the floor mentioned nor on the outer edge of the walls.
  • FIG. 1 shows a jet nozzle 1 for blowing a filament bundle 2 into an annular, rotatable and drivable stuffer box 3 with a blowing zone A for receiving and crimping the filament bundle and a treatment zone B for heating or cooling the crimped filament bundle and a dispensing zone C for dispensing of the crimped filament to a conveying element, in this case a suction drum 4 which can be rotated and driven by means of a shaft 38.
  • a jet nozzle 1 for blowing a filament bundle 2 into an annular, rotatable and drivable stuffer box 3 with a blowing zone A for receiving and crimping the filament bundle and a treatment zone B for heating or cooling the crimped filament bundle and a dispensing zone C for dispensing of the crimped filament to a conveying element, in this case a suction drum 4 which can be rotated and driven by means of a shaft 38.
  • the stuffer box 3 is provided on the circumference of a texturing wheel 5 which is rotatably and drivably mounted by means of a shaft 6.
  • the drive of it is not Part of the invention.
  • the stuffer box 3 comprises two air-permeable, annular walls arranged at a distance D from one another on the texturing wheel 5.
  • the walls in this example are two rows of needles 7 respectively. 8, which consist of individual needles 9 strung together, which are embedded in the circumference of the texturing roller 5. This forms that part of the circumference of the texturing roller 5, which is between the rows of needles 7 and 7, respectively. 8 is located, the bottom 10 of the stuffer box 3.
  • the jet nozzle 1 essentially comprises a filament insertion opening 12, through which the filament bundle 2 is introduced into the jet nozzle 1, and an air supply opening 13, through which a pressurized gaseous medium opens into a thread conveying channel 14, in which the thread bundle 2 is conveyed through the filament insertion opening.
  • the jet nozzle 1 now has two recesses 15 and 11 in the mouth part. 16, which give the mouth part a width d, which corresponds to the maximum width D of the stuffer box 3, as seen in FIG. 21. These two recesses expose the thread conveying channel 14 in the mouth part 11 along its length L (FIG. 20), so that the gaseous medium introduced in the thread conveying channel 14 is at least can already partially escape into the atmosphere in the region of the mouth part 11.
  • the filament bundle guided in this channel part begins to rub against the two remaining walls 17 and 18 due to the at least partially no longer available conveying medium, so that a delay in the conveying speed of the filament bundle arises, which leads to a compression of this filament bundle and thus a pre-crimping in this channel part.
  • FIG. 8 shows an enlarged detail according to the section lines V (FIG. 5) with the walls 7 and 8 formed from the needles 9, between which the mouth part 11 projects.
  • the part of the fiber feed channel 14 belonging to the mouth part 11 projects between the walls 7 and 8 in such a way that the filament bundle, as indicated in FIG. 1, in the upper half of the height H (radially delimiting the stuffer box 3) Fig. 8) is inserted into the stuffer box.
  • the crimped filament bundle 2.1 adhering to the needles 9 remains in this height range and is guided in this position through the treatment zone B and further into the delivery zone C.
  • a fiber bundle lifting means 19 projects between the walls 7 and 8 and under the crimped fiber filament bundle 2.1 held by these walls.
  • Such fiber bundle lifting means 19 are shown in FIGS. 15 to 18.
  • the fiber bundle lifting means in FIG. 15 is an endless belt 19.1 running along the bottom 10, which is deflected around a deflection roller 20.
  • the belt 19.1 lies snugly on the floor 10, so that the belt is moved smoothly by the texturing wheel 5.
  • FIG. 16 shows a stationary lifting wedge 19.2, which opens essentially tangentially to the floor 10 and is firmly connected to a fixed machine frame part 21.
  • 17 also shows a stationary lifting wedge 19.3, which is fastened to the machine frame part 21 and has a curvature 22 at the end facing the texturing wheel.
  • a lifting nozzle 19.4 as a lifting means, by means of which compressed air can be blown out in the conveying direction F in order to lift the crimped filament bundle located above the lifting nozzle out of the walls 7 and 8 and to feed it to the following conveying means.
  • the lifting nozzle is firmly connected to the machine part 21 and has a compressed air connection 37 (indicated by an arrow).
  • the air blown out in the conveying direction F emerges from correspondingly provided openings which are either arranged in the nozzle 19.4 in the corresponding end region or which are given by a very porous material.
  • Fig. 9 shows a variant of the walls 17 and 18 of the thread conveyor channel 14 in the mouth part 11 by the walls 17.1 and. 18.1 each have a concave curvature in order to improve the guidance of the crimped filament bundle in the mouth part 11.
  • FIG. 10 shows a variant of the needles 9 and the use of the mouth part 11 according to FIG. 8, in that the needles 9.1 of FIG. 10 are resilient and bear against the mouth part 11 with a prestress. This concern is shown schematically in FIG. 10 with the curvatures E and G.
  • the braking effect caused by this friction between the needles 9.1 and the mouth part 11 can be at least partially reduced by the finish present on the filament bundle and partly transferred to the mouth part 11. This also reduces the wear between the needles 9.1 and the mouth part 11.
  • FIG. 11 shows a variant of the arrangement of the needles 9 and. 9.1 compared to the arrangement in FIG. 5, by the needles 9, respectively.
  • 9.1 inclined backwards, viewed in the direction of rotation R of the texturing wheel 5, are arranged. This inclination is represented by the angle ⁇ .
  • the angle ⁇ must be determined depending on the length of the needles, the diameter of the texturing wheel and the arrangement of the fiber bundle lifting means 19. The inclination should be such that it is easier to lift out the crimped filament bundle.
  • Fig. 12 shows instead of the two rows of needles shown so far to form the walls 7 and 8, 7.4 for each wall. 8.4 a double row of needles, which, as shown in Fig. 12, arranged offset are.
  • Fig. 13 shows a further variant, in that the walls 7.5 and 8.5 each from a row of needles 9 and a perforated washer 23 and. 24 are formed, which the stuffer box 3 to the outside, i.e. closes at least partially in the radial direction of the texturing wheel 5.
  • the partial closure is done by the possibility that the two perforated washers 23 and. 24 can be shifted in the circumferential direction K or M, so that the holes 25 provided in the perforated ring disks are partially in series with the needles 9 and thereby restrict the air passage between the needles to a given extent.
  • the displacement of the washers 23 and. 24 in the directions of rotation K and M there is the possibility of at least partially controlling the ventilation of the crimped filament bundle located between the rows of needles.
  • Fig. 14 shows a variant compared to the rows of needles of FIGS. 5, 5a and. 8 to 10 by using lamellae 26 instead of needles.
  • the use of lamellae has the advantage that simpler slots can be provided in the texturing roller 5 instead of the fine bores required for the needles 9.
  • the lamellae 26 can be designed to be resilient, so that when the crimped filament bundle is lifted off in the lifting zone in a manner similar to that shown in FIG. 11, when the filament bundle is lifted off, it undergoes a bend which facilitates the lifting out of the filament bundle.
  • the walls 7.1 and 8.1 can be provided with an opening angle ⁇ , as shown in FIG. 4b.
  • Fig. 6 shows a variant instead of the needles 9 teeth 28, which the walls 7.2 or. 8.2 resp. form the stuffer box 3.2.
  • the teeth form part of a ring gear 29 which is mounted on the texturing wheel 5.2 for operation without slippage.
  • the teeth are provided in the radial direction.
  • FIG. 2 shows the same elements as FIG. 1.
  • the jet nozzle 1.1 of FIG. 2 has an angled mouth part 11.1 with respect to the jet nozzle 1 of FIG. 1, as is shown in FIGS. 22 to 26 is shown enlarged.
  • Another advantage is that through the angled walls 17.1 resp. 18.1 the bundle of filaments conveyed in channel 14 impacts against the angled wall 18.1 and thereby undergoes pre-crimping, in addition to the pre-crimping due to the escape of air from channel 14 in the region of the mouth part 11.1. and the resulting friction between the filament bundle and the walls 17.1 and 18.1.
  • the mouth part 11.2 is additionally provided with an air outlet opening 31, which is connected to a compressed air connection 32, for compressed air into the mouth part 11.2, in the direction of the filament bundle 2.1 emerging from the mouth part 11.2. to let in.
  • a compressed air connection 32 for compressed air into the mouth part 11.2 in the direction of the filament bundle 2.1 emerging from the mouth part 11.2. to let in.
  • Fig. 24 shows a similar embodiment as Fig. 23, but without the wall 18.1, on the other hand with the air outlet 31.1, which blows in a manner similar to the air opening 31 against the bundle of filaments conveyed by the channel 14, in order to deflect the bundle of filaments 2.1 without an impact effect to reach the wall 18.1.
  • FIG. 25 shows the jet nozzle 1.1 with a mouth part 11.3., Which differs from the mouth part 11.1 of FIG. 22 by a radius N in the wall 18.2. By means of this radius, the previously mentioned impact effect of the wall 18.1 can be controlled in an alternative manner to the air jet of the variant from FIG. 23.
  • Fig. 26 shows a variant of the mouth part 11.1 of Fig. 22, as the mouth part 11.4 in Fig. 26 instead of the walls 17.1 and. 18.1 of FIG. 22 a needle wall 17.2 or 18.2 has.
  • These needle walls consist of needles 33 lined up, which are provided with a small distance (not shown) from needle to needle, so that the air conveyed with the channel 14 can escape in the area of the needles 33 in order to further pre-crimp the filament bundle 2.1 in To let area of the needles 33 arise.
  • the first pre-crimping occurs in that channel part of the mouth part which forms a continuation of the channel 14.
  • FIG. 3 shows a variant of the arrangement of FIG. 2 in that a pair of rollers 34 takes over the crimped filament bundle 2.1 instead of the suction drum 4. Basically, only a simple conveyor roller could be provided instead of the roller pair 34.
  • the mouth parts 11.1, 11.2, 11.3, 11.4 and 11.5 of FIGS. 22, 23, 24, 25 and 26 have cutouts 15 and 16 corresponding to the channel 14 with the width d, as in the figures shown to expose.
  • FIG. 2 in FIG. 3 Another variant compared to FIG. 2 in FIG. 3 is that the fiber bundle lifting means 19 is not used, but that the filament bundle 2.1 is pulled out of the stuffer box 3 by the pair of rollers 34.
  • 1, 2 and 3 show in the area of the treatment zone B a means 35 for blowing a gaseous medium into the stuffer box 3 in order to treat the crimped filament bundle located in the stuffer box 3 either with heat and / or with cold .
  • a second means 35.1 (FIG. 3) with the same function can be provided, in which case the means 35 is used for the heat treatment and the means 35.1 for the cold treatment of the crimped filament bundle located in the stuffer box 3.
  • the second means 36 is mainly used when, as shown in FIG. 3, no suction drum 4 is used after the texturing wheel 5, on which the textured filament bundle 2.1 can be cooled further.
  • This suction drum 4 has, for example, a screen surface on the circumference, through which air is sucked through the screen surface in the region of the suction channel 36.
  • a fiber bundle lifting means 19 can also be used with the variant of FIG. 3.
  • the invention can be used, for example, for crimping polyamide 6 and 66 and for polypropylene, experience having shown that for a filament bundle of 500-3,000 d tex, a distance D (FIG. 21) of 3-4.5 mm, respectively. a cross section of the channel 14 of 10-20 mm 2 is selected.
